Abstract

Refers to the invention of a cargo moving system via cable (13), installed inside a fairing with a structure symmetrically parallel to the main laterals (06, 07); a cable gearing mechanical set (13) wherein there is a pinion axle (03), coupled to the reducer (08) and a break-motor (09), perpendicular to the laterals (06, 07) of the fairing, via the coupling's intermediary carcass (01 ); the cable lifters guide the cables, which go in through the guiding pipes (10, 11 ), and the pinion axle, with the individual involvement angle of eight hundred and seventy (870° ) degrees in the cable lifters' surface channels (02) showing the gearing set through the guiding pipe (12); a divisional structure (05) that warrants the sealing of the set's traction, separating the cable traction drum (13) from the cable winding drum (13).

Description

DOUBLE CABLING CARGO MOVING SYSTEM

The Invention Patent Descriptive Report for the moving of cargo, horizontally, vertically and in several angles via a cable gearing system, with the possibility of fixation at a distance anchoring point or at the cargo to maximize the use and the efficacy of this type of system in relation to the existing similar.

The present invention yields a new traction system to the cable, allowing the transportation of individuals and of cargo via the lifting of structures as elevators, pulleys, hoists, suspended scaffolds, baskets, chairs, and etc, and it can be used in Civil Construction, General Industry and in the food segment.

The cargo moving system acts via a set of traction forces, exerted by the brake-motor coupled to the reducer and to the pinion axle, whose movement triggers the synchrony of the dented cable lifters, resulting in the transmission of the movement. In the system, the breaking is performed via the break-motor, and via the reduction of the reducer.

In regards to the ample use of cargo lifting systems, there are some disadvantages, such as, e.g.: in the manual systems the capability of lower cargo and the reduced speed of displacement.

Some disadvantages of motorized systems: fixed coupling non-portable systems render handling and transportation of the traction system more difficult; mobile traction systems, which use internal space, reducing the floor space of the platform, or which use, significantly, outside space, rendering the assembly in narrow spaces unfeasible; systems requiring counterweights for operation, rendering assembly and disassembly more difficult; non-auto leveling systems, in which the leveling is manual; systems in which the traction cables are manually handled, resulting in the opening of the set; systems that have two traction cables, only, rendering the equipment less stable; systems operating the set of gears drily, resulting in wear and damaging the cable lifter; systems that operate the oiled set of gears, but pass the oil to the cable, considering the proximity of the cable with the oiled area; systems with lowers angles and friction coefficients; systems that lead to a deeper wearing of the cable considering the reduced diameter of the cable lifter, increasing the effort and, still; coupling systems that are lower than the platform, with constant falling of substances onto the platform, over the traction system.

The Invention Patent system allows the transportation of a larger capacity load, safely, and at a speed higher than the one of the manual traction system. The set anchors on the external portion of the structure that will be moved, and there is no reduction of internal space, and it does not take a significant lateral space, as it is a vertical gear system, coupled in parallel to the laterals of the platform, reducing the risk of damage to the system due o continuous use, and because it is suspended in relation to the platform.

Four cable lifters have two "V" shaped channels, reducing the wear and increasing their life cycle, the friction between the cable lifters occurs that 870 degrees of involved contact. A divisional structure separates the gearing drum from the cable-winding drum, allowing the cable lifter dents to remain oiled, and assuring that the cable does not contact the oiling elements.

The material used in the manufacturing of the system are ferrous metallic alloys, non-ferrous and fiberglass, or similar for the structural material. The characteristics of the mechanical material are ferrous metallic alloys, non-ferrous, welded sheets, polymeric or melted materials.

Following, aiming at a better understanding of the system in accordance with this present invention and as example, without restricting references, we describe one manner of performance, standard, manual or motorized, related to the annexed schematic drawings.

The Figure 01 is a frontal view, partially in a vertical section, schematic, of the cable traction, in accordance with the present invention, with an interior view of the coupling's intermediary carcass (01) open, and with the parallel symmetric structure of the main laterals with the gears mechanical set that triggers the cables (13), installed perpendicularly to the main laterals of the coupling's intermediary carcass (01); the pinion axle (03); the cable lifters (B, C, D, E); the deviation pulley (04); the guiding-pipes (10,11 ,12), and the divisional structure The Figure 02 is a complete superior view, in section, of the totality of the triggering system in the fairing, united to the reducer (08) and to the breaker-motor (09), via the coupling's intermediary carcass (01); the divisional structure (05) can be seen, separating the gearing drum from the cable- winding drum.

The Figure 03 portrays an enhanced perspective view of the main devices that compose the motorized system for cargo moving ; the coupling's intermediary carcass (01); the pinion axle (03); the deviation pulley (04); the divisional structure (05); the main laterals (06, 07); the reducer (08); the break-motor (09); and the guiding pipes (10, 11 ,12).

The figure 04 is a schematic frontal view that displays the general assembly in a building, indicating the route of the cable. The total angle of the cable winding is of 870 degrees, warranting the operation of the equipment without gliding. The Figure shows, also, that the upper supporting pulleys promote the automatic leveling upon the installation of the cable. Fastening the working cable (13) with the holding cable (14) increases scaffold's stability. The Figure 04 shows, still, the guiding pipes (10, 11 , and 12).
